Answer:
The equation for height is

Step-by-step explanation:
we are given
An iron ball is bobbing up and down on the end of a spring
So, height function must be trigonometric in nature
So, we can use formula

now, we can find A , B and D
Calculation of A:
maximum height 46 inch
minimum height =18 inch
so,

Calculation of B:
It takes the ball 2 seconds to go from its maximum height to its minimum height
So, half of time period is 2 sec


now, we can use period formula

we can find B



Calculation of D:
Max=46
min=18


now, we can plug these values into formula
and we get

Answer:
The point was reflected over the x-axis and was translated down 12 units.
The greatest common factor of 12 and 15 is 3 because it is the greatest number divisible by both 12 and 15.
Answer:
The answer is 13 1/8ft3
Explanation:
Substitute into the formula:
Volume = 3 1/2 x 2 1/2 x 1 1/2
= 7/2 x 5/2 x 3/2
= 105/8
= 13 1/8 ft3
Answer:
D. 12p + 36 > 480
Step-by-step explanation:
The number of pages read is the sum of the number already read (36) and the product of the number read each day (p) and the number of days (12). Rylee wants this number of pages read to be more than 480.
__
The inequality expressing a sum greater than 480 is ...
12p +36 > 480 . . . . choice D
